1. Prepare the Oven and Baking Dish: Setting the Stage for Baking

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Grease Baking Dish: Lightly grease a 9×13 inch baking dish with butter or non-stick cooking spray.

2. Prepare the Vegetables: Choosing and Prepping Your Greens

1. Choose Your Vegetable: This recipe offers a choice between broccoli florets and frozen spinach.
2. Prepare Broccoli (if using): If using fresh broccoli florets, bring a pot of salted water to a boil. Add the broccoli florets and cook for 1-2 minutes until they turn bright green. Drain immediately and rinse with cold water to stop the cooking process.
3. Prepare Spinach (if using): If using frozen spinach, make sure it’s completely thawed. Place the thawed spinach in a clean kitchen towel or several layers of paper towels and squeeze out as much excess water as possible. This is crucial to prevent a watery casserole.

3. Combine the Main Ingredients: Building the Flavorful Filling

1. Combine Ingredients: In a large mixing bowl, combine the cooked chicken, cooked and chopped bacon, your prepared vegetable (broccoli or spinach), minced garlic, ranch dressing, ½ cup of shredded mozzarella cheese, and ½ cup of shredded cheddar cheese.
2. Mix Well: Stir all the ingredients together until they are well combined and the chicken is evenly coated.
3. Optional Ranch Seasoning: If you want an extra boost of ranch flavor, add 1-3 teaspoons of dry ranch seasoning mix to the bowl and stir well.
4. Alternative Mixing Method: For even easier cleanup, you can mix all the ingredients directly in the greased 9×13 inch baking dish.

4. Transfer to Casserole Dish: Assembling for Baking

1. Pour Mixture: Transfer the chicken and vegetable mixture into the prepared 9×13 inch baking dish.
2. Spread Evenly: Spread the mixture out in an even layer using a spoon or spatula.

5. Add the Cheese Topping: A Golden, Bubbly Finish

1. Sprinkle with Cheese: Sprinkle the remaining ½ cup of shredded mozzarella cheese and ½ cup of shredded cheddar cheese evenly over the top of the casserole.

6. Bake to Perfection: Creating a Cheesy, Golden-Brown Casserole

1. Bake: Place the baking dish in the preheated oven.
2. Baking Time: Bake for about 15 minutes, or until the cheese topping is melted, bubbly, and lightly golden brown.

7. Cool and Serve: Enjoying Your Low-Carb Creation

1. Cool Slightly: Remove the casserole from the oven and let it cool for a few minutes before serving. This allows the filling to set slightly.
2. Serve Warm: Serve the Easy Low Carb Chicken Casserole warm and enjoy!
